G&G SGR 556 M-LOK G3 Split Gearbox Optical ETU Deans Wired AEG




G&G SGR 556 M-LOK G3 Split Gearbox Optical ETU Deans Wired AEG

G&G's first split gearbox design - G&G's G3 gearbox opens up "shotgun" style, providing easier and faster access to your internals. 

Optic sensor module - No more need for a selector plate. An optical sensor detects which firing mode your selector is in for a more accurate and durable selector.

Patented power cut system - After firing the last BB from your magazine the power to your gun will be cut. This feature works with any standard M4 AEG magazine. After reloading, simply depress the bolt catch to resume firing.

Modular QD electronic board - The MOSFET can easily be removed and replaced without disassembling your gearbox. The MOSFET sits on top of the lower gearbox and is held in with a single screw. 

Pre-cocking - Enabling optional 80% pre-cocking reduces the time between pulling the trigger and firing your BB by half, giving you the advantage to hit your opponent before they hit you.

Adjustable trigger travel - 3 adjustable trigger travel modes. Progressively shortening the necessary trigger pull needed to fire.

Programmable trigger mode - Even though this replica comes with a remote controller to program different firing modes, you can still use the programmable trigger to set different settings such as 3 or 5-round burst firing modes.

Uses a standard V2 8mm ball bearing

Innovative hop-up chamber module - The 36 tension steps on this updated hop-up design are adjusted by a screw at the front of the gas block, giving you precise and stable control over your hop up.
